Hi all,



I have a '97 with CA emissions. I made 2 sheet metal plates to block the crossover pipe as a temp fix about two weeks ago. Truck seems to run better and get better mileage, could be my imagination though, only one tank since then.



I have read that my intake is heavily restricted, something to do with exhaust recirculation. I don't understand how an engine with a pressurized intake can recirculate exhaust gasses, but oh well.



I installed gauges today, EGT and boost. I noticed a lot of soot on the plug in the intake when I took it out.



Anyway, I was wondering what I should do here, if anything. Does this restriction increase my egt's? Do I need a new intake, and can I get one for a non-CA truck with my CA engine number? Should I remove my intake and have it cold-tanked ASAP to remove soot, or is it not that big-a-deal?



I saw a listing on ebay for an "intake plenum"?, I assume its the first/top part of the intake that the EGR valve bolts to, off of a '94. Would that fit my truck and eleminate the restriction?



Thanks for all your input.

Go to a Cummins West dealer and get the 49 state intake. No blocking plate needed for the intake. Check the fitting on the back of the afc for soot fouling. you will have to remove the fitting.

This intake is not restricted like the CA version. It will cost about $70. 00. Do not worry about the soot in the head/intake manifold,this new intake will do the job,trust-me ;)
 
update

I just got off the phone with my cummins northwest dealer. He cannot sell me the 49 state intake because of my engine number. He did give me the name of a shop in my area that does work with these engines, called The Power Shop. I was wondering if anyone has had any experience with this shop?



thanks for your input

It is illegal ($10,000 fine) for a shop to remove your emissions equipment. You have two choices: buy a federal intake and install it yourself, or buy an egr intake that has been milled out so it doesn't restrict the flow. You can either hook up the egr or not. The new 49 state intake is cheaper, the other way is potentially legal.
 
Hey Ben-

I ordered a non-ca intake and told them it was for my 95 dodge (advice from other members). The part number for the intake is 3931516 and cost around 60 bucks.

Hopefully this helps! Also my EGT dropped about 250 degs cruising on the freeway unloaded!!

well I called the shop, and they have a take off intake for $25. I think I'll go pick it up this weekend. Thanks for all your help.
